Description
Casticin is a polymethoxyflavone reference compound supplied as ROTICHROM® HPLC material for chromatographic and analytical laboratory use. It is defined by CAS number 479-91-4, the empirical formula C₁₉H₁₈O₈ and a molar mass of 374,32 g/mol, providing a transparent chemical identity for identification, calibration and method development work. The substance is offered in a 20 mg glass pack, giving sufficient material for stock preparation and repeated HPLC comparisons while remaining economical for specialised standards. Available from manufacturer Carl ROTH in the ROTICHROM® HPLC series, casticin supports phytochemical profiling, natural-product research and quality-control assays that require a characterised flavonoid reference. The glass presentation aids secure handling and organised storage of the solid in the laboratory. Research groups and analytical service labs can incorporate this standard into existing HPLC methods for peak assignment, system checks and quantitative or semi-quantitative studies involving casticin.

Questions about Casticin, ROTICHROM® HPLC, 20 mg, glass
What is this article?
Casticin, ROTICHROM® HPLC, 20 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Lab chemicals.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is HPLC & LC-MS grade solvents. The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
